Lopes says a contractor that requires cash or a check made out to an individual is a red flag.

“The goal is they want to come and get the money as quickly as they can, so it’s not surprising that if they get somebody on the hook, they’re going to try to reel them in as quickly as they can,” said Lopes.

Andrew has learned and is considering small claims court.

“I hope people hear about this and don’t get ripped off by this guy,” said Andrew.

Any contractor, including a window coverings company, doing work above $500 must be licensed with the CSLB.

You’re only required to put 10 percent or $1,000 down, whichever is less.

All contractors are required to carry a license, about the size of a credit card, with them. Ask to see it. If they’re hesitant to show you, that’s another red flag.
